Specification of Letters Patent. Patented June 27, 1922 i 'Applicationled'eptenibei 29, 1919. Serial No. 327,132.

T 0 @ZZ whom t may con cera f Be it known that I, sMUs Pn'rnnsnN, acitizen of the United States, residing in the city of St. Louis andState ofMissouri, have invented certain new and novel Improvements inrlrolley-Pole Adjusters, of which the following isa speciication.

My invention relates to trolley-polead j listers, and has for its objectto provide a deviceadapted to bc applied to a: trolleypole adjacent thetrolley wheel and `so 'constructed that a movable member thereofniay beactuated by pullingon the trolley-rope for quickly replacing thetrolley-wheel in contact with the trolley-wire after it has left thetrolley-wire.

YVith the above and other objec'tsin view, the invention consists in thenovel construetion, arrangementA andcombination of parts, hereinafterdescribed and finally pointed out in the claims hereto appended.

Referring to the accompanying drawings forming a part of thisspecification wherein like characters of reference denote similar partsthroughout the several views: v

Fig. 1, is a side elevation of a'trolley-pole` equipped with myimprovement. the same being shown in its normal position in full lines,and in its uppermost adjusted .posi-y tion in dotted lines.

Fig. 2, is a detail of the forward extension end of the movable guidemember.

F ig. 3, is a top plan view of Fig. 1.

Referring to the drawings, the reference character 1 designates atrolley-pole. 2, a socket member fixed to the trolleypole having abifurcated end 3. 4, a trolley-wheel rotatably mounted in the bifurcatedend 3 of the socket member 2. 5, is the usual trolley-rope fixed to thesocket member' 2 for actuating the trolley-pole 1, and 6 indicates thetrolley-wire.

In carrying out the aim o1 my present :invention, I employ a pair ofsuitable clampmeinbers 7 and 8, which are securely held in a clampedposition upon the socket-member 2 by means of the fastening devices 9.Each clamp-member 7 and 8 is provided with a stop, or lip 10 adapted toengage the shoulder 11 of the socket-member2 to prevent any possiblechange of the clamp-members 7 and 8 from slipping down thesocket-member,`

should the fastening devices 9 loosen a little Jfrom any cause.

A relatively long movable guidemember 12 having an opening 13 ispivotally connected to the ears 14 of the clampfniember 8,

by means of the pin 15. Therear end of the.

guide member 12 is provided with a pair of outwardly diverging guidearms 16.

The forward end oit-the guidemember 12 is provided with an `extensionmember 17 Yhaving an opening 18 and the forward extremity-19 'ot' theextension member 17 is provided with a rope opening- 20. The extension17 is arranged at a suitable angle to the longitudinal axis olf theguide member 12, while a rope opening20is alsoarrangedr at a suitableangle to the longitudinal axis ofthe extension member 17 The`trolley-rope 5, ixed tothe socket f member 2, first passesthrough theopening. 18, of the extension member 17 and through Y to the uppermovement of .the trolley wheel,

come into contact with one of the spreadingY guiding arms 16, thuspreventing the trolley wheel from rising to a higher elevation. Now, allthat is necessary for the conductor to do to replace tlietrolley-wire 6upon the trolley-wheel 4, is to pull rearwardly upon the trolley rope 5,which will cause the trolley-pole to stand still while at the saine timethe pulling movement on the rope rwill bring the extension member 17 tothe substantially vertical position shown in Fig. 1 and thereby in turnraise the guide-member 12 and diverging guide-arms 16 to the upwardlyand rearwardly inclined position shown in Fig.

1. The upper movement of the guide arms 16 will cause the trolley-wire 4to be raised at the saine time, and the guide arms 16, in

being raised, willv gradually crowd the trolley-wire 4 to the center ofthe guide-arms so that by the timel the arms have been fully raised thetrolley will be in alinement with the groove of the trolley wheel. Now,as thetrolley rope 5 is slackened after the trolley-wire 4 has beenraised by the guide arms 16, the trolley-pole, when released will riseand the trolleywire will ride in the groove of the trolley-wheel, as ismanifest.

From the foregoing, it is evident that when the trolley wheel 4 jumpsout of engagement with the trolley-wire 6, that to replace thetrolley-wire upon the trolley wheel, the operator merely pullsrear-wardl y on the trolley-rope 5 which causes the guide arms 16 toraise the trolley wire and bringit into a center line with the groove ofthe trollej,'-wl1eel where it will seat itself again after thetrolley-pole has been permitted. to raise by letting loose of thetrolley-pole 5.

lt will be observed that the arms of the bifurcated end Bof thetrolley-polewill act as a stop for the members vl2 to engage when thedevice is actuated so as to limit the upward movement of the membersThis is clearly shown in dotted lines in fligr. 1. When the arms ylEZarein the position shown in dotted lines .in Fig. l, observed that part ofthe trolley-wheel -l passes through the opening 13.

The many advantages of the herein described invention will readilysuggest themselves to those skilled inthe art to which it appertains.

I do not desire to be understoodas limiting myself to the details ofconstruction and arrangement as herein described and illustrated, as itis manifestthat variations and modifications may be made in the featuresof construction and .arrangement in the adaptation of the device to`various condi'- tions of use without departing from the spirit andscope of my invention and the terms of the following claims, hence l.wish it to be understood that l Areserve the right to make any suchchanges Sor modifications as may fairly fall within the scope of theappended claims when fairly construed.

What l claim is:

llln means for replacing a trolley-wire upon ya. trolley-wheel7 anangular movable it will be` member pivotally connected to a trolley-poleand having an opening to receive the trolley-l avith trolle -wire for re)lacino' the ltrollevwire upon the trolley-wheel,

2, ln combination with atrolley-poleand trolley-wheel, a guide-memberpivotally connected tothe trolley-pole, said guide member having' a pairof rearwardly and downwardly extending spaced arms to form an opening'for the trolley-wheel to enter when elevated, forked arms extending`,from 'the free ends of said spaced arms, said guide member *having apair of forwardly extending diverging arms forming` a rope loop andterminating downwadly and forwardly to form a second loop through whichloops a trolley-rope is adapted to pass for connection with thetrolley-pole so that when the rope is pull-ed rearwardly it will slip inthe rope loops and at the same time lower the forward end of the guidemember and raise the rear end thereof to an elevated position forreplacing a trolley-wire upon the trolleywheel. i

ln testimony whereof7 l .have 'hereunto signed my name to the sieciiication.
